Because in many cases it takes $thousands to refurbish a used boat to the condition needed for an offshore voyage. Sometimes you end up spending as much on a new outfitted boat as you do on used. There are advantages to both. Some people don't have all the up front cash, so buying used and upgrading over time works well. Some people prefer to purchase new for fewer hassles like replacing engines, sails, electronics, etc.. Some people want a custom design or features. It's a personal decision, just like buying a new car or used, Honda or Mercedes. That's why there are so many choices new and used. It's definitely a good thing.
